neuron scal of movment

if found something that i try to correct but no effects…
I stream from axis movement to my model, and when i want to scale the character system scale vector movement in space in wrong way.
so when character have scale 1 when it walking around the 3d space movement match to size of steps, but after scale (uniform scaling for all axis) step is shorter then movement along axis.
I try scale in object, by null transform and by deformers, any ideas?
